As shown in fig. 5 and 6, the fastener 191 is, for example, a screw, and cooperates with the nut 192 to lock the fixing member 17 and the temperature controller 16 on the air deflector 12, the nut 192 serves as a mounting structure, and in this embodiment, also serves as a spacer 18, and is dual-purpose, so that the number of accessories is reduced, the temperature controller 16 is mounted without adding a new step, only by locking the screw once, the assembly process is simple and efficient, and the flange has a certain thickness, so that the fixing member 17 is lifted, and the lifted distance of the fixing member 17 is equal to the thickness of the flange.

When the fixing member 17 includes the collet 171 and the mounting portion 172, the burring is abutted at least against the mounting portion 172, and of course, in order to enhance the supporting effect of the fixing member 17 as a whole, the area of the burring may be increased so that it is abutted more against the bottom of the fixing member 17.

Further, in one embodiment, the liquid expansion thermostat 16 includes a temperature sensing probe that is disposed corresponding to the heat generating region 141 of the heat generating tube 14.

As shown in fig. 2, the heating tube 14 is formed by a tube, two ends of the heating tube 14 are cold end areas 142, and the rest is a heating area 141, and by arranging the temperature sensing probe corresponding to the heating area 141 of the heating tube 14, the temperature measuring accuracy of the temperature controller 16 can be improved, and the influence of the lower temperature measured by the temperature controller 16 on the food processing effect can be avoided. The heating tube 14 can be fixed on the air deflector 12 through the heating tube bracket 143, and a certain distance is reserved between the heating tube 14 and the temperature controller 16, so that the heating tube 14 is prevented from affecting the temperature measurement accuracy of the temperature controller 16.

The technical solution protected by the present utility model is not limited to the above embodiments, and it should be noted that, the combination of the technical solution of any one embodiment with the technical solution of the other embodiment or embodiments is within the scope of the present utility model. While the utility model has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the utility model and are intended to be within the scope of the utility model as claimed.
